MILLING WELLBORE CASING |
摘要 |
A cutting insert for milling wellbore casing in a downhole environment includes a body having a cutting face and a chip-breaking face. The cutting face and chip-breaking face are oriented at a face angle relative to each other, the face angle being between 75° and 130°. As the wellbore casing is milled, swarf is formed and work hardened. Further deformation of the swarf and movement along, or in contact with, the chip-breaking face breaks the swarf into chips that are readily flushed away or transported within the wellbore. |
